PlCKER-ROD FOR MOLDERS.

SPECIFICATION forming part of Letters Patent No. 415,179, dated November 12, 1889.

Application filed September 12, 1888. Renewed August 21, 1889. Serial No. 321,456. (No model.)

To all whom it may concern:

Be it known that I, HERMAN R. TRAVERS, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Picker-Rods for Molders, of which the following is a specification.

My invention relates to a picker-rod for molders. This tool is used by moldcrs of metal for removing or lifting patterns from the sand mold.

The invention is illustrated in the accompanying drawings, in which Figures 1 and 2 are side views of the picker-rod. Figs. 3, 4c, and 5 are views of the catch-plate with which the rod engages. Figs. 6 and 7 are views of the picker-rod and catchplate, showing the manner of applying the same to a pattern.

The picker-rod A has near one end a shoulder 1), which comes in contact with the top surface of a catch-plate O, which is secured to the pattern. Two arms (Z are at the extremity of the picker-rod, and these arms are separated from the said shoulder b by a space e, which is a little greater than the thickness of the catch-plate on the pattern. In the present instance the said two arms (Z have the form of a half-button, (see Fig. 1,) the contour being a half-circular line which is intercepted by a straight diainetrical line. The form, however, of the arms is immaterial. The catch-plate O is secured to the pattern f by screws, or in any desired way, and has a slot (1 for the passage of the two arms (Z on the extremity of the rod, and on its under surface said catch-plate is provided at each side of the slotwith an incline 6'. These two inclines are reverse with respect to each other that is to say, one pitches in a direc-- tion opposite the other.

Vhen it is desired to employ the pickerrod to lift a pattern from the sand-mold, the arms cl at the end of the rod should be inserted in the slot d of the catch-plate, and then a quarter-turn should be given the rod,whereby the two arms d will take under the inclines e. and the shoulder l) on the rod will be drawn down in close contact with the top of the catch-plate. By the means here described the rod becomes rigidly connected with the catch-plate and serves perfectly to lift the pattern.

The sand will not choke the recess g below the catch-plate, and will not interfere with the insertion of the arms d nor with the described quarter-turn whieli they should make.

Having described my invention, I claim A picker-rod for lifting patterns, having at its extremity two arms and a shoulder near said arms, but separated therefrom by a space, in combination with a catch-plate having a slot and provided on its under surface with an incline at each side of the slot, for the purpose set forth.

In testimony whereof I aflix my signature in the presence of two witnesses.

HERMAN R. TRAVERS.
